Given numbers are 664, 816, 826, 458

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(664, 816) = 67728

GCD(664, 816) = ( 664 x 816 ) / 67728

= 664 / 816

= 664

Step2:

LCM(8, 826) = 3304

GCD(8, 826) = ( 8 x 826 ) / 3304

= 8 / 826

= 8

Step3:

LCM(2, 458) = 458

GCD(2, 458) = ( 2 x 458 ) / 458

= 2 / 458

= 2

So, Greatest Common Divisor of 664, 816, 826, 458 is 2
